Plot of graph is not possible without softwere. But the minimum distance where change in potential is zero is 308.67pm and the potential energy at this separation is -194.642K. Graph can be plotted by MATLAB software.
4) For Ne, the parameters of the Lennard-Jones 6-12 potential are ε/Kg-35.6 K and σ-275 pm....
2. The ε and σ values for Lennard-Jones potential of xenon are found to be 1.77 kJ/mol and 4.10 Å, respectively. The ε and σ values for Lennard-Jones potential of argon are found to be 0.997 kJ/mol and 3.40 A, respectively. Plot the L-J potentials for Xe-Xe and Ar-Ar interactions, which potential has a deeper minimum (i.e. stronger interatomic interactions)? Why?
14-5. Using Eqs. (14-14) and (14-17), calculate the van der Waals constants a and b for nitrogen. For u(r), assume a Lennard-Jones 6-12 potential with ε and σ given in Table 12-3. Compare these calculated values to the experimentally determined values, a 1.39 x 106 cm atm/mole and b-39.1 cm/mole. Such poor agreement is quite typical, simply indi- cating the inadequacy of the van der Waals equation. 14-2 THE VAN DER WAALS EQUATION We start with Eq. (14-3), and take...
